# 18 - Agile, Real-Time and Live Collaboration

Play The Event agile module: sprint management, tasks with Kanban and Gantt, WebSocket for live updates, domain events, real-time notifications and activity tracking.

## What you'll learn

- Domain-driven design: Aggregates (Sprint, TaskEvento) enforce all business rules, while domain events decouple state changes from side effects
- Real-time first: WebSocket with STOMP and SockJS fallback ensures every connected user sees changes instantly, regardless of their network environment
- Multi-view flexibility: Kanban, Gantt, and list views serve different mental models without duplicating data or logic
- Collaborative estimation: Planning Poker with Fibonacci story points brings team consensus to effort estimation
- Resilient notifications: Async, post-commit event handlers ensure notification failures never affect core business operations
